This union represents the bit fields in the Control Register 1.
Read the register into the d32 member then set/clear the bits using the b elements.

结构体成员变量说明

◆ [struct]

struct { ... } spi_ctrb_data::b

Register bits.

◆ d32

uint32_t spi_ctrb_data::d32

Raw register data.

◆ nrdf

uint32_t spi_ctrb_data::nrdf

Number of Data Frames.
When TMOD = 10 or TMOD = 11 , this register field sets the number of data frames to be continuously received by the spi. The spi continues to receive spi_slenrial data until the number of data frames received is equal to this register value plus 1, which enables you to receive up to 64 KB of data in a continuous transfer.
When the spi is configured as a spi_slenrial slave, the transfer continues for as long as the slave is selected. Therefore, this register spi_slenrves no purpose and is not present when the spi is configured as a spi_slenrial slave.
